Experimental Research
The notation for this design is
R O X O
R O O
What is basic experimental design?
A researcher uses a specific innovative teaching method with one section of a course and uses the traditional teaching method with the other section of the class. This is what type of design?
What is a cohort design?
Another way to refer to non-experimental designs, which are often used to characterize a phenomena or examine a relationship between variables.
What is pre-experimental research?
P is < 0.05
What is probability level?
or
What is confidence level?
What is external validity?
This type of design is used when the researcher is unsure of the impact of the pre-test on participants but believes the pre-test provides pertinent information to the study.
What is Solomon four-group design?
R O X O1
R O O2
R X O3
R O4
This type of design occurs over a period of time and the experimental group acts as it's own control group.
What is times-series design?
An OTR working in the school system is interested in determining the relationship between hours of sleep at night and academic performance in high school students.
What is correlational research?
A researcher is interested in comparing interval data.
What is a t-test?
A researcher wanting to ensure that a study's sample has an equal opportunity to be in the experimental group as in the control group should use _____________.
What is random assignment?
What is single-blinded randomized control study (RTC) ?
A researcher designs a study when research participants all receive the treatment and then experience a period of time that they do not receive the treatment.
What is one-group pre-test-post-test design?
or
What is quasi-experimental lacking control?
An OTR is working at an inpatient acute rehabilitation facility and collects information on one patient with Parkinson's disease over a period of 3 weeks.
What is quantitative case study research?
A researcher wants to examine correlation of parametric data.
What is Pearson r?
A researcher attempts to eliminate any irrelevant influences on a study's design.
What is control?
What type of research design is appropriate when one is interested in investigating at least two independent variables and their interaction with the dependent variable?
What is a Factorial design?
This type of research design is MOST APPROPRIATE when a researcher wants to study naturally occurring situations or it is unethical to use a control group.
What is quasi-experimental?
Studies in which the dependent variable has already occurred for example a disease or disability are considered _______________
What is retrospective?
A researcher compares the means of 4 groups in a study.
What is an ANOVA?
What is interrater reliability?
What type of research design does this notion indicate?
R O X O1 O2
R O O3 O4
What is pre-test - post-test design with follow-up?
What is level 3?
An OTR sent out a questionaire to individuals with rheumatoid arthritis (RA) to determine the impact of RA on quality of life.
What is survey research?
r = -0.9
What is a negative correlation?
What is as one score goes up the other goes down?
nominal and ordinal data are considered __________
This is important to consider because ___________
What is non-parametric data
It helps determine the type of statistical testing to use.
